Figure 7

Changes in cell function in hONS cells treated with ZnO nanoparticles. For each ZnO treatment at each time-point (2 h, 6 h and 24 h), the responses of hONS cells from donors A, B, C and D, each seeded in three replicate wells, were averaged and expressed as the percentage of time-matched untreated cells set as 100%. Data used to generate this figure, and associated standard errors of means and statistical significance, are supplied separately in Additional file 3: Table S2.
